Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for spraying or sowing granular materials such as fertilizers, pesticides and seeds which are mixed with water and sprayed or sowed in a field.

[0002]

2. Description of the Related Art Conventionally, a sprayer or a seeder for spraying or sowing granular materials such as fertilizers, pesticides and seeds has been known. In these sprayers or seeders, the granular material contained in the hopper is fed in a dry state, and is naturally dropped, or sprayed or seeded in the field by wind force, discharge blades or the like. That is, the granular material is sprayed or sown in the field in a dry state.

[0003]

However, in order to secure a certain working width in the above-mentioned conventional spreader or seeder, there is a problem that a large number of feeding devices are required in the free fall type. Further, in the wind-powered type and the discharge blade type, the influence of the difference in the conveying distance and the influence of the wind make the distribution of the spraying amount or the seeding amount uneven, and the seeds are easily damaged during the conveying or discharging. There was a problem.

As described above, since there are many problems in the spraying or seeding method or device using the existing sprayer or seeder, there are many problems in the present invention. An object of the present invention is to provide a method and a device for spraying or sowing particulate matter, which enables efficient and appropriate spraying of pesticides and liquid fertilizers by mixing with and spraying or sowing in the field.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides: (1) Fertilizers, agricultural chemicals, granular materials such as seeds are mixed with water, and the mixed water is conveyed and sprayed to a field or (2) Fertilizers, pesticides, seeds, and other granular materials stored in the hopper were mixed in a prescribed amount with water sent by a pump using a mixer, and this mixed water was conveyed to a spraying device. And spraying or sowing in the field.

[0006]

By the above means, the method and apparatus for spraying or sowing the granular material of the present invention have the following operations. Wider spraying or seeding is possible with less feeding device than the conventional one, so that the manufacturing cost can be reduced and the spraying amount or seeding amount can be easily adjusted. Compared to the air transfer type, the influence of the difference in the transfer distance is less. Since the air is naturally dropped from the spray pipe, the unevenness of spray due to the wind in the atmosphere is reduced. Less damage to seeds during transportation. In addition, when seeding directly in flooded rice, the effect of burial of seeds by water flow is expected.

[0007]

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. 1 and 2 are a side view and a rear view showing a first system according to the present invention. Reference numeral 1 is a paddy field working vehicle using a passenger car body such as a riding type rice transplanter as a bogie.

A water absorbing section S1 having a water absorbing pump (jet pump or the like) P1 is provided below the front part of the paddy field vehicle 1, and the submerged water 4 is sucked up from the water absorbing section S1 by the operation of the water absorbing pump P1. A strainer is provided at the water inlet of the water absorbing portion S1 to prevent the infiltration of foreign matters in the submerged water 4. The water sucked up from the water absorption part S1 is sent by the pump P1 to the water tank T1 mounted on the rear part of the paddy field vehicle 1 via the elevating link 6. Water tank T1
A filtration net 7 is provided on the upper part of the tank to remove soil particles and foreign substances from the water sent from the pump P1, and the cleaned water is temporarily stored in the water tank T1.

The water stored in the water tank T1 is sucked up by the spraying pump P2 through the strainer S2,
It is sent to the spray pipe 8. When the amount of water stored in the water tank T1 becomes a certain amount or more, the excess water 9 is returned to the paddy field. Behind the water tank T1, a granular material tank T2 for accommodating granular materials such as fertilizers, pesticides, seeds, etc. is mounted, and the granular material fed out from the tank T2 through the feeding device F by a constant amount is the pump P2. Is mixed with water in the mixer M provided in the pipeline on the way to the spray pipe 8
Sent to and sprayed in the field. Reference numeral 10 is a pressurizing path when a jet pump is used.

As shown in FIGS. 3 and 4, the spray pipe 8 is
Is provided with a large number of spray holes 8a, 8a ... At predetermined intervals along the lower part of the length direction.
Protrusions are provided on the sides of the a, 8a ... Opposite to the moving direction of the mixed water, and the mixed water of the particulate matter sent to the spray pipe 8 is evenly distributed in the field through the spray holes 8a, 8a. It is supposed to be sprayed. Also, as shown in FIG. 5 and FIG.
It is also possible to connect and connect the base end portions of the conduits 11, 11 ... To the respective spray holes 8a, 8a ... Of the spray pipe 8 so that their respective tip discharge holes face the paddy field 5. When configured in this way, it is particularly suitable for direct seeding work of seed watering.

In the first system (embodiment) as described above, the paddy field vehicle 1 drives the front wheels 2 and the rear wheels 3 to perform the spraying work while traveling in the paddy field 5. Water absorption part S
For the 1st odor, the submerged water 4 is sucked up by the operation of the water absorption pump P1, sent to the water tank T1, and temporarily stored in the water tank. The water stored in the water tank T1 is supplied by the spray pump P2.
It is sucked up by and is sent to the spraying pipe 8, and in the process, it is mixed in the mixer M with granular materials such as fertilizer, pesticides, seeds, etc. fed out from the granular material tank T2 by a fixed amount through the feeding device F. , Mixed water is sent to the spray pipe 8 and sprayed uniformly on the field through the spray holes 8a, 8a.

As described above, only one feeding device F is provided, and a fixed amount of granular material such as fertilizer, pesticide, seed, etc. is mixed with water and sprayed broadly or sowed through the spray pipe 8. Therefore, it is possible to significantly reduce the manufacturing cost as compared with the conventional one provided with a large number of feeding devices. In addition, it is possible to easily adjust the spraying amount or the seeding amount of the granular material.

Further, as compared with the conventional air-conveying type in which the granular material is conveyed by air pressure and dispersed, since it is conveyed by the water flow, the influence of the difference in the conveying distance is lessened, and the accurate spraying operation can be performed. Furthermore, from the spray pipe 8 to the spray holes 8a, 8a
Since it naturally falls through ..., the unevenness of spray due to the wind in the atmosphere is reduced. Furthermore, when seeds are sprayed, the seeds are less likely to be damaged during transportation because they are mixed with water before being transported. In particular, as shown in FIG. 5 and FIG. 6, the distribution pipes 8 are provided with the conduits 11, 8a ...
When 11 ... are connected and the discharge hole faces the field 5,
Seeds can be sprayed in a fixed position during direct seeding of flooded rice and conduit 1

The second embodiment (system) of the present invention shown in FIG. 7 is a form in which the water absorbing portion S1 of the first embodiment shown in FIGS. 1 to 6 is not used, and is accommodated far more than the water tank T1. It has a large storage tank T3. Then, a large amount of water is stored in advance in the tank T3, and the water is sucked up by the spraying pump P2 and sent to the spraying pipe 8. Other configurations are similar to those of the first system.

In the device for spraying or sowing the granular material of the second system, a large amount of water is stored in the water storage tank T3 in advance, the water is sucked up by the spraying pump P2 and sent to the spraying pipe 8 side, In the process, granular materials such as fertilizers, agricultural chemicals, seeds, etc., which are fed out from the granular material tank T2 through the feeding device F by a fixed amount, are mixed in the mixer M, and mixed water is sent to the spray pipe 8. From the spray holes 8a, 8a ... Needless to say, the first and second systems described above can be used not only for seeds and fertilizers or pesticides having conventional particle diameters, but also for large-sized granules such as microcapsules or powders.

[0016]

As described above, according to the method and apparatus for spraying or sowing the granular material of the present invention, the granular material such as fertilizer, pesticide and seed is mixed with water and the mixed water is conveyed to the field. Since it is sprayed or seeded, the following effects can be obtained.

Since it is possible to perform wide-spreading or seeding with a feeding device that is smaller than the conventional one, it is possible to reduce the manufacturing cost. Further, the amount of spraying or the amount of seeding can be easily adjusted. It is possible to reduce the influence of the difference in the transport distance as compared with the conventional air transport type. Since it naturally drops from the spray pipe, it is possible to reduce uneven spraying due to wind. Less damage to seeds during transportation. In addition, the seed burial effect due to the water flow during direct sowing of paddy rice can be expected.
